Problem of the automatic thermogradient stabilization of the constructive elements sizes is discussed. The actual problem is the determination of the control algorithm controlled heat sources, providing them with the minimum possible number of minimal deviation from the desired temperature in a given cross-section design. The proposed procedure for solving optimal control of temperature distribution in the numerical design of its implementation, allows obtaining results that are suitable for approximate implementation in on-Board computers, Autonomous systems and significantly reduce thermal deformation component of the measurement error.
The paper discusses oil distillation into target products with regard to the unclear separation effect. As the input data, the table of physical and chemical properties of narrow fractions is used. The problem is solved using the dynamic programming method. The methodology is realized in the authors' software product. Primary oil processing takes place mostly in CDU (crude distillation units). There oil is separated in a number of target products: gasoline, kerosene, diesel, vacuum tower bottoms. Oil is characterized by a true boiling temperature (TBT) curve reflecting the relation between the temperature and distillation cuts' fractions. In practice, TBT is a compilation of narrow fractions with end points [ , ]
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
